Abstract

Perceptual and neural attenuation for self-generated (SG) sounds at clearly audible intensities is well established, yet recent work suggests a reversal at near-threshold levels, with SG sounds perceived as louder. Here we tested whether this near-threshold perceptual enhancement is mirrored by enhanced early auditory cortical responses. Healthy adults (N = 47) performed an auditory intensity disc…
